Logweeder

Logweeder is a reliable and free log analyzer tool that automatically categorizes common events, scans UN*X logs (syslog), and detects uncommon events without any manual intervention. The software is particularly useful in analyzing syslogs as these logs are typically recorded one event per line in most UN*X systems.

Logweeder works by scanning syslog outputs (e.g. /var/log/messages) and identifying uncommon events by first learning common log patterns from existing log files. The software groups similar log entries and generalizes them as a regular expression pattern, allowing the user to generate patterns that classify logs of known types.

With Logweeder, users can quickly and accurately identify logs that are not categorized to any known type, indicating that it may be an uncommon entry. This drastically reduces the time spent manually analyzing logs, allowing users to focus on resolving any issues identified.

Overall, Logweeder is a powerful and intuitive software that helps IT teams analyze and manage logs with ease. Its ability to automatically detect uncommon entries, combined with its user-friendly interface, makes it a must-have tool for any IT professional.
